                   float p2,
                   float p3)

Method Detail

setTextOrientation

public void setTextOrientation(int orient)

Set the text orientation for the display of the limits and value if appropriate.
Acceptable values are G4P.ORIENT_LEFT, G4P.ORIENT_RIGHT or G4P.ORIENT_TRACK
If an invalid value is passed the ORIENT_TRACK is used.

Parameters:

orient - the orientation of the number labels

setTickLabels

public void setTickLabels(java.lang.String[] tickLabels)

This method is used to set the text to appear alongside the tick marks.
The array passed must have a minimum of 2 elements and each label (element) must have at least 1 character. If these two conditions are not met then the call to this method will be ignored and no changes are made.

Parameters:

tickLabels - an array of strings for the labels

setShowTicks

public void setShowTicks(boolean showTicks)

Set whether the tick marks are to be displayed or not. Then recalculate the track offset for the value and limit text.

Overrides:

setShowTicks in class GValueControl

Parameters:

showTicks - the showTicks to set

setTrackOffset

public void setTrackOffset(float offset)

The offset is the distance the value/labels are drawn from the centre of the track.
You may wish to tweak this value for visual effect.

Parameters:

offset -

getTrackOffset

public float getTrackOffset()

Get the visual offset for the value/label text.

getValueS

public java.lang.String getValueS()

If we are using labels then this will get the label text associated with the current value.
If labels have not been set then return null

Overrides:

getValueS in class GValueControl

mouseEvent

public void mouseEvent(processing.event.MouseEvent event)

Overrides:

mouseEvent in class GAbstractControl

draw

public void draw()

Overrides:

draw in class GAbstractControl
